I'm coming to you guys as a last resort. I recently upgraded my PC to windows 8.1 from a ~2 month old install of windows 8. On windows 8, PC slept predictably when set to 30 min. I had two "powercfg /requestsoverrides" set via command line to ensure that this happened, however. Now, upon upgrading, PC will not sleep predictably when set to an idle interval of 30 min., even if "powercfg /requests" shows "none." for every category. PC will sleep automatically if power options are: display shutoff set to 1 min, and sleep PC set to 2 or 3 min; OR if ethernet cable is unplugged from computer (with display/sleep set to 5/15 min). Disabling IPv6 and the Homegroup fix, both mentioned in this thread, did not work: http://forums.anandtech.com/showthread.php?t=2329266. Virus scans via windows defender and malwarebytes are negative, all drivers are up to date, and PC sleeps fine manually.

Do you all have any advice for me? I really just want to make sure that if computer wakes up due to scheduled tasks (or my cat), that it will be able to fall back asleep.

Check out the latest post by John on Page 2. He's posted quite a bit on that, so I may delve deeper into that later. I already clicked the "leave Home group" button in the settings, to no avail. Dell will get back to me on Monday after more consultations with MS and their other tech teams. They tried a lot, without much success on my machine.

That didn't work for me. I did change settings so that all the computers are now on the same homegroup, and sharing things appropriately - to no avail. Computer still remains awake unless network card is unplugged or sleep times are super short.

As an example of the kind of programs to look out for. Burning software for example can prevent sleep. Even VoIP programs can prevent sleep. For example Ventrilo will prevent the computer from going to sleep.

Thank you, I'm in the midst of trying your suggestions. However, when I ran the /energy command, the generate report will not come up. IE says File Not Found (Cannot display page). How do I overcome this?

Copy the file, and place the copy on your desktop - the file is generated in a place where the program needs admin privileges to open it. On the desktop IE should be able to open it fine.

Gotcha, that took care of it. I got 5 errors, 23 warnings, 22 informational. Here are the errors, any feedback to help resolve this problem would be eternally appreciated!

Which may be attributable to the problem.

My computer supports S3, but not S1 or S2, which is normal, right?

Also, I just observed it idle, and it seemed that right when it was supposed to enter sleep, the screen cut back on again. Two errors popped up from MpTelemetry that look like they might have something to do with windows defender - which seem to have happened right when the PC was supposed to go to idle. If you want to see these, I can try to upload them.

I have overrides for the powercfg /requests that seem to have typically caused this thing in the past, which were srvnet and "realtek audio driver"

That looks like the crux of the issue there. The high average CPU usage is concerning too. That implies a lot of active tasks. One of those might be preventing sleep. Use Task Manager to track that down.

WinKey + X > Control Panel (Small or Large Icons) > Power Options > Balanced (should be selected with a radio button) > Change plan settings > Change advanced power settings > Restore plan defaults > Sleep > Sleep after > make sure on battery and plugged in now have a value (the restore defaults should have done it)

Totally normal. S1 = PoS or Power on Suspend. It derived out of APM and was the Sleep method of the 90s before Suspend To RAM (S3) came into being. Few systems still give that option anymore (often requires mucking in the BIOS to even turn it on).

I've never seen S2 supported by a device.

Maintenance might help you then. It might have been kicking off a scheduled Defender scan right as the PC was trying to go to sleep. That's just a arrow in the dark at the moment though.

The past 3 times I have let my computer idle, it has slept after the time set in power options, and the /requestsoverrides I set before updating to 8.1 are working as well. I checked by opening an audio stream, and the computer still idled to sleep. Perhaps the maintenance helped? I haven't yet attempted the /scannow or /restorehealth commands yet, but things seem to working pre-update now (*knock on wood*). I'll update further if necessary. Thanks for your help, Ryu!

I have 2 Win 8.1 setups, one on a Surface Pro, another in a VirtualBox VM (hosted on Linux Mint). After upgrading both to 8.1, both had issues show up in under Maintenance, including thinking that certain device drivers were not fully installed. It seems to me that Windows should tell me in more obvious ways when it's not "happy".

There's no telling what they're fixing/breaking, but both are crunching away...

I just realized I forgot to mention this to you earlier: I deliberately set the power plan to not sleep AFTER this problem surfaced:

Power Policy:Sleep timeout is disabled (On Battery)The computer is not configured to automatically sleep after a period of inactivity.

I made the changes in the current plan, regardless of whether it's plugged in or not since if it does actually go to sleep, then it freezes and I have to do a hard reset and lose my work. So now I leave my laptop plugged in and it never goes to sleep mode automatically, as desired. My biggest problem is the fact that closing the lid won't get it into sleep mode. Black screen, lights still on, no response. Same thing with shutdown. It successfully restarts, but hangs on shutdown much the same way I close the lid.

You might also look to see if there is a firmware (BIOS) update for your laptop. May seem an arbitrary thing, but system firmware controls the implementation of the ACPI. 8.1 may be exposing a bug in the firmware.

Thank you for the suggestions. I know it's a process of elimination, and we're definitely getting closer! I'm reading about more people afflicted with the same thing daily. It's no surprise MS pulled the 8.1 RT upgrade from their servers on Saturday since so many people were experiencing catastrophic issues. Surface PCs being bricked, completely unable to boot. Nice one, MS.

I'll have to try the suggestion you linked concerning restorehealth and scannow cmds.

I'm pretty sure I updated the BIOS firmware to latest (probably after 8.1), but I'll check. I've got a feeling it was the Solid State drive firmware that I got (fyi, no hard drive on my dell, just solid state. Not sure if this info helps).

Will send another update later this evening when I come home from work.
